Description

E-flow 40 is a very widely used cadmium free silver brazing filler metal. It offers a combination of medium melting temperature and flow characteristics. It can be used to fill gaps that cannot be tightly controlled. These properties make it a popular choice as an alternative to the higher silver content E-Flow filler metals.

It is widely used as a general-purpose silver brazing filler metal as well as in joining copper to steel in refrigeration pipework. It should be noted that this filler metal contains tin and may be described as being ‘hot-short’. It should not be quenched from high temperatures (in excess of 300°C) and care should be taken when it is used to braze components with widely differing coefficients of thermal expansion as in both cases cracking of the joints may occur.

Optimum joint gaps at brazing temperature are 0.075-0.2mm.
